Adisseo, a manufacturing for monogastric feed enzymes, has announced the results of recent feed trials on fattening pigs.

Using Rovabio as part of a reformulation strategy increases digestibility up to 1.8 percent and the addition of Rovabio in feed increases slaughter pig weight by 2 kg. In the case of low energy diet reformulated with Rovabio, net energy which is entirely available for growth, is improved by 1.5 percent.

Feeds with various levels of corn, wheat and barley were tested for energy digestibility on 8 ileo-anastomosed pigs, using a latin square design and the same methodology as for amino-acid digestibility. Similar improvements are observed for amino acid digestibility, allowing feed reformulation at a lower level of energy and amino-acids, without changing animal performances.

Consequently, the inclusion of Rovabio reduces feed prices by 2-3 percent or up to EUR5.8 (US$8) in reformulated feed without any change in ingredient limitations.

Costs can be further reduced by using a higher inclusion of grain byproducts with high fibre content and low price, said Pierre Dalibard, Adisseo's Global Technical Manager.

Rovabio also increases significantly daily intake and consequently average daily gain, from 1,4 percent to 5,9 percent during the first phase, depending on the type of diet. Then, on global fattening period, the average daily gain is increased from 2,4 percent (+2,1 kg live weight), with a wheat-barley-soymeal, to 3,7 percent (+2,5 kg live weight) with a corn-soymeal.
